IMPROVEMENT IN WINDMILLS.

To aZZ whom it may concern.-

Be it known that I, JOHN MYERS, of Dallastown, in the county of York and State of Pennsylvania, have invented a new and Improved Windmill; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part Figure 1 represents a front elevation of my invention. Fig. 2 is a plan or top view of the same. Fig. 3 is a partial side elevation ofthe same.

Similar letters of referenceiu the three views indicate corresponding parts. l

The object of this invention is to produce a simple, cheap, and effective device for the purpose of making the power of the wind available for cutting firewood or for driving small machines-such as churns, washing-machines, tof-that are generally used in farmhouses and by others.

This invention consists in the arrangement `of a wind-wheel provided with au annular rim that is secured to the outer ends of the wings, and forms a belt-wheel from which motion is imparted to the saw-spindle or other device, in combination with a hinged rotary post, which is raised or lowered by a windlass or other suitable device in such a manner that by raising and turning said post t0 the wind the wind-wheel is brought in working position and at the same time the belt is stretched, and

4when the wind-wheel is not to be used it can be conveniently turned down, so as to release the belt and stop the motion of the whole device.

It consists, further, in the arrangement of a a secondary anged wind-wheel attached to a transversely-sliding adjustable arm, in combination with the belt running from the main wheel to the saw-spindle or other device in such a manner that an additional power is obtained, and at the same time the. tension of the driving-belt can be regulated at pleasure.

To enable those skilled in the art to make and use my invention, I will proceed to describe its construct-ion and operation with reference to the drawings.

The main wheel A is provided with an annular rim, B, which is secured to the outer edge of the wings'a, and it rotates on a sta-` tionary axle, C, which projects from and is firmly inserted into the upper end of the post D. This post is stepped'into a suitable socket, b, for that purpose made and provided, so that the same can freely turn and that the wheel A can be set to or from the wind, as may be desired. Said post is made of two parts, c d, the upper part, c, being connected with the lower part, d, by a pivot, e, so that the same, together with the wheel, can be turned up or down in a plane at right angles with the axle C. Its position is regulated by a windlass, f, that is'attached to the lower part, d, of the post D, and which connects by a belt or chain, g, with the end of the hinged parte of the post D. Vhen the main wheel is lowered down, the belt g winds on a quadrant, h, that extends from the end of the hinged section of the post up to a level with the pivot e, and by these means the belt is prevented from getting entangled or twisted. treme edge of the quadrant h a pin, t', rises, which carries a small vane, j, for the purpose of determining the' correct position of the mai n-wheel in relation to the wind.

From the rim B of the main wheel A a belt, E, extends to a pulley, F, on the saw-spindle,

or to thedriving-pnlley of any other machine Yor implement to be operated by the force ofthe wind. Thisbelt may be sufficiently stretched when the main wheel A is turned up to its Working position; but in order to be able to regulate the tension of said lbelt at pleasure, and at the saine time to increase the power of the device, a secondary wheel, G, is added, which is constructed similar to the main wheel with a rim, k, which is secured to the outer edges of its wings. rlhe axle Z of this wheel has its bearings in a forked arm, m, which is secured in a mortise in the edge of the lower portion of the post D by means of a wedge, n, being so arranged that said arm can be drawn in or out and fastened in any desired position.

`Vhen the belt E is in its place and the main wheel A is raised and the forked arm with the secondary wheel G is inserted, the surface of this secondary wheel will bear against the belt, as clearly shown in Fig. l, and by moving the arm m in the direction of the arrow marked upon it in Fig. 1 the tension of the belt can be increased at pleasure. At the same time the action of the wind on the wings of the sec- From the Aupper exondary wheel increases the power or" the wh ole device.

This wind-wheel may be used to drive a ci rcular saw, and in this case the belt E runs directly to the saw-spindle, and a small table supported by arms which extend from the lower part of the post D forms the support for lthe wood to be cut. A large quantity of kindling-wood can thus be cut in a comparatively short time and with little labor. `It is obvious, however, that my windmill can be used with equal advantage for operati ng churns or washing-machines or other similar devices or implements.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The arrangement of hinged rotary post D and windlassf, in combination with belt E, running over the annular rim B ofthe windwheel A, constructed and ,operating substantially in the manner and for the purpose shown and described.

2. The arrangement of the secondary windwheel G and transversely-sliding adjustable arm m, in combination with the belt E and wind-wheel A, constructed and operating substantially in the manner and for the purpose specified.

JOHN MYERS.
